' UNITED STATES PATENT OFFICE.

GEORGE BOWER, OF ST. NEOTS, COUNTY OF HUNTINGDON, ENGLAND.

PROCESS OF DEPOSITING METALS UPON THE SURFACES OF IRON AND STEEL COATED WITH MAGNETIC OXIDE.

SPECIFICATION forming part of Letters Patent No. 270,004, dated January 2, '1t 83. Application filed February 20, 1882. (No specimens.) Patented in England June 23, 1881, No. 2,;50.

land, and residing at St. Neots, in the county of Huntingdon, England, have invented certain Improvements in Apparatus for Deposit in g Metals upon the Surfaces of Iron and Steel Coated with Magnetic Oxide, (for which I have obtained a patent in Great Brila-in, No. 2,750, dated 23d day of June, 1881,) of which the following is a specification.

, My invention relates to an improved method of depositing metals upon the surfaces of iron and steel; and it consists in first coating such surfaces with magnetic oxide, and then effecting the deposit of the desired metal by rubbing the surface of the article or object (coated with magnetic oxide) with a brush or device having its wires or filamentsfcomposed of or coated with the metal which it is required to deposit. I I

The particular method of first coating the iron or steel with magnetic oxide forms no part of my present invention, as any wellknown method maybe employed for that purpose.

By the mode described of depositing the required metal by first coating the surface with magnetic oxide, and then brushing this coated surface with wires of the metal to be deposited, I obtain results equal to those produced by the processes known as gilding, bronzsilver, the brushing of the nncoated surface with a brush of German-silver is ineffectual,

'but if the iron is first coated with magnetic oxide and the brush is then applied to the coated surface, a deposit is readily formed.

I claim as my invention- As an improvement in the art of coating metals, the process of depositing metals upon iron-0r steel, which process consists in first coating the metal with magnetic oxide, then brushing such coated metalwith wires or filaments composedot' or plated with the metal to be deposited, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I

. GEO. BOW-ER.
